In 1986, 5 commercial bean sites near Holyoke (Colorado, USA) were treated with 4 sprays of cupric hydroxide every 7 to 10 days beginning at least 2 wk. before flowering to (1) sample for the presence of Cu resistance in naturally-occurring epiphytic populations of Pseudomonas syringae pv. syring...

Investigations during 1984 and 1985 demonstrated that Pseudomonas syringae pv. phaseolicola (Psp) and Pseudomonas syringae pv. syringae (Pss) occur as epiphytes on dry beans in Colorado. Populations of syringae-type pseudomonads (STPs) were detected on volunteer bean plants throughout northeaster...

Cassava, one of the world's major food crops is grown throughout the tropical regions of the world. Cassava originated in the neotropics; it was introduced into West Africa from Brazil by slave traders in the 1500's, and taken to Asia during the 17th century. Consequently the greatest diversity o...

Maize is becoming the major food crop around Lake Victoria. Major constraints to its production are Striga, stem borer, and declining soil fertility. Innovative integrated technologies have been developed: the push pull system (intercropping with Desmodium and surrounded by Napier grass), soybe...

The insecticidal activity of Maruca vitrata (F.) multi-nucleopolyhedrovirus ( Mavi MNPV) combined with oil from neem, Azadirachta indica Juss and Jatropha curcas L. (Euphorbiaceae) was studied under labo- ratory and fi eld conditions against three key insect pests of cowpea, Vigna unguiculata (L....
